Yeah you're right about the video card specs. The rest is 16 GB Ram and a modest Intel i3-12100F 3.30 GHz processor. Actually I wanted to finish what I started and installed your Camila and Heather models. And what I wanted to render looked like this:

After 2 min of loading the scene (
I had ruled out absolutely everything else. I also used the Cut scene addon - it puts Iray Plans to improve rendering time, but still ) I can't even start rendering the scene with 12 models
There is probably a way to stage render and assemble the whole scene, but I don't have time to experiment.
When you load in a scene, what you're seeing in this screenshot it stored in your system RAM. When you go to render it, all the VISIBLE parts are loaded onto your video card's VRAM, which takes time as the slowest transfer is over the system bus from system RAM into video card VRAM.
I would render the left half first, then the right half. So, anyone that appears on one half, even a body part, have them visible. Make the characters that don't appear not visible. No need to delete anything, if you make anything not visible, it won't be loaded onto the video card. You can use the spot render tool (ALT+SHIFT+C) which allows you to draw a square around an area and it will only render that portion. I think there are settings where you have to set it to save what you render. So you draw a square around one half, hiding everything not visible, render, rinse and repeat for the other half. I mean, that is A LOT of characters to render.
Also, if you want to try and render the whole scene at once again, remember, that in any scene subsets that I upload, I will often raise the quality level of the characters so their textures are high resolution = much more data for this many characters! You may do well by lowering their quality down a tad and it may still work.
For example, in a scene I just rendered yesterday for a character I created named "Sasha", if you look at her Mesh Resolution after clicking her then checking General and Mesh Resolution in the Parameter's tab, you'll see that I have her SubDivision Level set to 2, and her Render SubD Level set to 3. Her original settings on the default model was probably 1 for Subdivision Level and 2 for the Render SubD Level. For a scene like yours, I would lower them all down to 1 and 2 and then see how you do.
